Permission management system for data accessing and method thereof

Abstract

The invention discloses a permission management system for data accessing and a method thereof, applicable to operating system. The method of permission management for accessing data comprises the steps of: first, monitoring an unoccupied drive letter in operating system; then, detecting a drive letter request event and actively executing an authorizing procedure to produce an access right of the drive letter; and stop monitoring the drive letter and allowing a user to access data corresponding to the drive letter according to the access right.

1 . A method of permission management for accessing data, applicable to an operating system, comprising steps of:
 monitoring at least one drive letter that is unoccupied in the operating system;   detecting a drive letter request event of the drive letter and actively executing an authorizing procedure to produce an access right of the drive letter; and   stopping monitoring the drive letter and allowing a user to access data corresponding to the drive letter according to the access right.   
     
     
         2 . The method of permission management for accessing data as claimed in  claim 1 , detecting the drive letter request event of the drive letter is achieved by a callback function. 
     
     
         3 . The method of permission management for accessing data as claimed in  claim 2 , wherein a function address of the callback function is registered in the operating system such that while the drive letter request event is taking place, the operating system calls the callback function according to the function address. 
     
     
         4 . The method of permission management for accessing data as claimed in  claim 1 , wherein detecting the drive letter request event of the drive letter is achieved by listening to a device change message of the operating system. 
     
     
         5 . The method of permission management for accessing data as claimed in  claim 1 , wherein detecting the drive letter request event of the drive letter is achieved by I/O polling. 
     
     
         6 . The method of permission management for accessing data as claimed in  claim 1 , wherein the access right comprises: denying accessing, or allowing reading, writing, executing or combinations thereof. 
     
     
         7 . The method of permission management for accessing data as claimed in  claim 1 , wherein the authorizing procedure comprises password authorization or biometrical authorization. 
     
     
         8 . The method of permission management for accessing data as claimed in  claim 7 , wherein the biometrical authorization includes fingerprint identification, iris recognition, retinal recognition, palm shape recognition, face recognition, voice recognition, vein recognition or DNA identification. 
     
     
         9 . The method of permission management for accessing data as claimed in  claim 1 , further comprising steps of:
 detecting a drive letter releasing event of the drive letter; and   monitoring the drive letter.   
     
     
         10 . A permission management system for data accessing, applicable to an operating system, the permission management system comprising:
 a monitoring module monitoring at least one drive letter that is unoccupied in the operating system;   a detecting module detecting a drive letter request event of the drive letter;   an active authorizing module actively executing an authorizing procedure to produce an access right of the drive letter while the drive letter request event is detected by the detecting module; and   a data accessing module allowing a user to access data corresponding to the drive letter according to the access right;   wherein the monitoring module further stops monitoring the drive letter while the authorizing procedure is completed.   
     
     
         11 . The permission management system for data accessing as claimed in  claim 10 , wherein the detecting module detects the drive letter request event of the drive letter by a callback function. 
     
     
         12 . The permission management system for data accessing as claimed in  claim 11 , wherein a function address of the callback function is registered in the operating system such that while the drive letter request event is taking place, the operating system calls the callback function according to the function address. 
     
     
         13 . The permission management system for data accessing as claimed in  claim 10 , wherein the detecting module defects the drive letter request event of the drive letter achieved by listening to a device change message of the operating system. 
     
     
         14 . The permission management system for data accessing as claimed in  claim 10 , wherein the detecting module detects the drive letter request event of the drive letter achieved by I/O polling. 
     
     
         15 . The permission management system for data accessing as claimed in  claim 10 , wherein the access right comprises: denying accessing, or allowing reading, writing, executing or combinations thereof. 
     
     
         16 . The permission management system for data accessing as claimed in  claim 10 , wherein the active authorizing module executes an authorize procedure by password authorization or biometrical authorization. 
     
     
         17 . The permission management system for data accessing as claimed in  claim 16 , wherein the biometrical authorization comprises fingerprint identification, iris recognition, retinal recognition, palm shape recognition, face recognition, voice recognition, vein recognition or DNA identification. 
     
     
         18 . The permission management system for data accessing as claimed in  claim 10 , wherein the detecting module further detects a drive letter releasing event of the drive letter and informs the monitoring module to monitor the drive letter.
